C# byte[]与Image类型相互转换

1.将Image转换成byte[]

        public byte[] ImageToByteArray(Image image)
        {
            MemoryStream imageStream = new MemoryStream();
            image.Save(imageStream, System.Drawing.Imaging.ImageFormat.Jpeg);
            byte[] imageContent = new Byte[imageStream.Length];
            imageStream.Position = 0;
            imageStream.Read(imageContent, 0, (int)imageStream.Length);
            return imageStream.ToArray();
        }

2.将byte[]转换成Image

        public Image ByteToImage(byte[] byteImage)
        {
            MemoryStream stream = null;
            try
            {
                using (stream = new MemoryStream(byteImage))
                {
                    Image bitmapnew = ((Image)new Bitmap(stream));
                    return bitmapnew;
                }
            }
            catch (ArgumentNullException ex)
            {
                throw ex;
            }
            catch (ArgumentException ex)
            {
                throw ex;
            }
        }
